1. Goal of affiliationWe reciprocate because it sends a message about our sociability. We try to elicit liking from other people by behaving in ways we guess will be attractive, like agreeing with them or complimenting them.
In the most part humans are social so they want to be liked. Rejection is no fun and we'll do almost anything to avoid it.
Not only do we want approval from specific people, we also want it from society at large (see this article on conformity). We want the things we do, think and believe to be broadly in line with what others do, think and believe. It's not impossible to be different, but it is difficult.
The techniques of liking and reciprocity mentioned above both clearly play on our desire for affiliation, as do many other techniques of persuasion and influence. Most people are joiners and followers so influencers like to give us something to join and someone to follow.
2. Goal of accuracy
People who don't care about doing things correctly never get anywhere in life. To achieve our goals in what is a complicated world, we have to be continually trying to work out the best course of action.
It could be accuracy in social situations, such as how to deal with the boss or how to make friends, or it could be accuracy in financial matters like how to get a good deal, or it could be accuracy in existential matters. Whatever the arena, people are always striving for the ‘right' answer.
Influencers understand our need to be right and so they try to offer things that appeal to our need for accuracy. For example, experts or authority figures influence people heavily because they offer us a ‘correct' view or way of doing things, especially one that we don't have to think too carefully about.
The techniques of social proof and scarcity both nag at our desire to be accurate because we assume other people are likely to be right and we don't want to miss out on a bargain.
3. Goal of maintaining positive self-concept
People want to protect their view of themselves because it takes a long time to build up a semi-coherent view of oneself and one's place in the world.
We work hard to keep our world-views intact: we want to maintain our self-esteem, to continue believing in the things we believe in and to honour whatever commitments we have espoused in the past. In an inconsistent world we at least should be self-consistent.Persuaders and influencers can leverage this goal by invoking our sense of self-consistency. A trivial but instructive example is the foot-in-the-door technique. This is where an influencer asks you to agree to a small request before asking for a bigger one. Because people feel somehow that it would be inconsistent to agree to one request and then refuse the next one, they want to say yes again.
People will go to surprising lengths to maintain their positive view of themselves.
